Description
Technical field
The invention belongs to LED frame processing technique field, sewage disposal dress after specifically a kind of LED frame is tin plating
Put.
Background technology
LED frame is copper, it is necessary to the electroplating surfaces with tin in LED frame carrys out antirust, needs to be passivated after plating, is passivated
It is dried again afterwards, containing chromium, it is necessary to be discharged again after handling in the sewage after current passivation.
The content of the invention
In order to solve the above problems, the invention provides a kind of tin plating rear sewage-treatment plant of LED frame, the device are effective
The chromium in sewage is separated.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
The present invention is a kind of tin plating sewage-treatment plant, including waste water treatment box afterwards of LED frame, is provided with waste water treatment box
Two collection acid adjustment casees, the stirring vane of motor driven stirring is provided with each collection acid adjustment case, in each collection
Insertion sets PH sensor and sulfuric acid feed pipe in acid adjustment case, is provided between each collection acid adjustment case and waste water treatment box
Several discharge nozzles, reducing agent feed pipe and lime feed pipe are set respectively in the both sides of waste water treatment box, in waste water treatment box
Lower end is provided with outlet pipe.
Further improvement of the present invention is：Stillpot is provided with waste water treatment box, stillpot is connected by connecting rod and cylinder
Connect, the screen cloth for filtering out sediment is set in the lower end of stillpot, activated carbon filter layer is set in the lower section of stillpot, precipitated
The inside of groove is additionally provided with several blocks, and sediment is separated, and sediment material taking mouth is additionally provided with waste water treatment box.
The beneficial effects of the invention are as follows：The sewage of the present invention is entered back into treatment box after the regulation of acid adjustment case and gone back
Former precipitation process, the sewage in acid adjustment case are flowed into by multiple pipelines, can promote sewage and the reducing agent and stone in treatment box
The mixing of ash, the sewage-treatment plant add reducing agent into waste water, Cr6+ are reduced into Cr3+, Ran Houzai in acid condition
Lime is added, it is generated chromium hydroxide precipitation in the basic conditions, is separated so as to remove chromium ion.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
